Maybe. Apple's product strategy for chip generation introductions hasn't been consistent. Just two generations of examples: the M5 was introduced first with the iPad Pro, Vision Pro, and the lowest-end MacBook Pro. We had to wait several months for other products. The M3 cycle was also . . . not an exact pattern that was used prior nor has been since.
Bloomberg (Gurman) is today stating that while the Mac Studio, for example, was initially slated for an upgrade mid this year, that now October is the earliest because of component shortages. If the M6 is going to be released (in perhaps some products like the iPad Pro, a low end MacBook Pro, and/or the iMac) in the fall . . . does it make sense to release a M5 Max/M5 Ultra in a Mac Studio at all? It seems hard to say from history. Regardless, just in the era of Apple Silicon, not a single desktop model has received consistent yearly upgrades like the iPhones and certain MacBook and iPad models have. The Mac Pro (now dead, but last was upgraded to the M2 Ultra), Mac Studio (didn't have M3 Max nor M4 Ultra), Mac mini (didn't have M3 nor M3 Pro), nor iMac (didn't have M2). There is just not enough consistency to be sure what Apple is planning at this point, I think.
